I'm riding along minding my own business - I'm as far to the right as I can be, not obstructing traffic, and moving at a half decent pace (guessing around 18+) when there is suddenly a pretty hard thud off of the back of my right side rib cage. Knowing that I was hit with something, I look back to see an almost full large frozen plastic chocolate milkshake container skidding along behind me. Because I didn't see it coming, I had the thrower narrowed down to 2 possible vehicles - a Mustang and a white Van. Now pissed as hell and realizing that the cars will probably get stuck in traffic at a busy stop sign about a half mile away, I accelerated and pressed the bike as fast as I could go. I managed to catch up to the vehicles fairly winded but still out for blood just as the Mustang was hitting the stop sign. Still not knowing for sure who through it, I thought about trying to jump in front of the Mustang, blocking both cars, and then figuring out who did it. Looking over at the side of the van as I'm riding past, I noticed that milkshake drops were sprayed on the side of the van, and realized that this was confirmation of the vehicle that did it. I get up to the passenger side window as the Mustang pulls away, and am surprised to see a female, mid 20's, in the passenger seat. Loudly asking "you like to throw stuff?" as I'm dismounting, the "girl", after a slight pause (she didn't expect me to catch up...) says "Yea, and FU" with a big smile as the driver (who I never saw) runs through the stop sign. Nice! What totally wonderful people!!!

Knowing that there's no way I'm going to be able to catch them again and really pissed at myself now as well for not at least kicking the side of the van or having something to throw, I did look at the license plate before mumbling to myself "why, what's the point...". When I get home and tell the story to my wife (who's always much more levelheaded than myself) states that I should have never been looking to draw blood in the first place and I should have been only looking to get the plate and call the police.

So, I have to ask in the event something like this happens again - If I had gotten the plate, would calling the Police have done any good?
